How did failing eyesight change Georgia O’Keeffe’s work in her later years?

By the mid-1970s, Georgia O’Keeffe’s failing eyesight forced her to abandon oil painting, except when she could work with assistance. This physical limitation necessitated a significant shift in her artistic practice during her later years.1

With the guidance of her friend and associate, sculptor Juan Hamilton, O’Keeffe adapted by exploring new mediums. Hamilton taught her to work with clay, and with his assistance, she produced objects in that medium as well as in watercolor. Despite these challenges, she continued to work independently in charcoal, pastel, and pencil until 1984, when declining health eventually led to her move to Santa Fe.1
